Under pseudo-first order conditions, the reaction follows first order kinetics with respect [isoleucine]. At lower values of [CTAB] (≤40.0×10-4 mol dm-3), the catalytic effect of cationic micelles of CTAB may be due to the incorporation/solubilization of isoleucine and MnO-4 into the interfacial region of Stern- and palisade layer.In contrast, at higher values of [CTAB] (≥40.0×10-4 mol dm-3), the inhibitory effect was observed due to the dilution.Thermodynamic parameters were computed by studying the reactions at different temperatures (303-333 K). Plausible mechanisms are suggested.  ISSN : 0193-2691  Journal Name : Journal of Dispersion Science and Technology  Volume : 32  Issue Number : 8  Publishing Year : 1432 AH 2011 AD  Article Type : Article  Added Date : Tuesday, September 20, 2011  Researchers Researcher Name (Arabic) Researcher Name (English) Researcher Type Dr Grade Email Maqsood Ahmad Malika Malika, Maqsood Ahmad Researcher Doctorate   Rayees Ahmad Sheikh Sheikh, Rayees Ahmad Researcher Doctorate   شعيل أحمد الثبيتي AL-Thabaitia, Shaeel Ahmed Researcher Doctorate sthabiti@hotmail.com عبدالله يوسف عبيد Obaid, Abdullah Yousif Researcher Doctorate aobaid@kau.edu.sa ظهير خان Khan, Zaheer Researcher Doctorate drkhanchem@yahoo.co.in Files File Name Type Description  30513.pdf pdf Abstract Back To Researches Page
